在linux上生成privateKey，

openssl genrsa -out rsa\_private\_key.pem 1024

根据privateKey生成publicKey

openssl rsa -in rsa\_private\_key.pem -out rsa\_public\_key.pem -pubout

将java私钥或公钥转换成pem格式，php代码：

<?php
 class entry {
 var $pub_key;
 function redPukey()
 {
 $pubKey = "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";
